Title: Bubble memory driving circuit
Inventor: KANEKO YOSHIYA
IPC: G11C11/14
Filed: 1982-11-12
Abstract: PURPOSE:To improve the current waveform characteristics of a driving coil by connecting a diode with specific polarity between control electrodes of the driving coil and a switching element for control and improving the off characteristics of switching characteristics. CONSTITUTION:When switching elements Q0, Q3, etc., are turned on by a timing pulse P1, the driving coil L is connected to a high-potential power source VCC to increase the current flowing through the coil L, and when the elements Q0 and Q3 turn off, the coil L serves as a power source by being discharged to flow a triangular wave current to the coil L. The diode D10 having the polarity opposite to that of the current flowing through the coil L is connected between the coil L and base of the element Q3; when the element Q3 is off, the potential at a node (a) is lower than the voltage of a low-potential power source VEE and the excessive accumulated potential of the base is neutralized to turn off the element Q3 speedily and completely. Consequently, a shift in the discharge timing of the coil L is prevented and the characteristics of the triangular wave flowing through the coil L are improved to increase the phase margin, so that magnetic bubbles are transferred stably at a high speed.

Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a recording erasing device for a reversible magnetic recording medium capable of realizing the simplification and the miniaturization of structure at low cost. SOLUTION: By supplying a current signal outputted from a controller 16 to a coil 7, magnetic field is generated. The magnetic field forms AC magnetic field in a magnetic substance 8, the AC magnetic field passes through magnetic particles 3 inside the medium F, so that an eddy current flows inside the particles 3. Joule heat is generated inside the particles 3, by the eddy current, so that the viscosity of a dispersion medium 4 is lowered. By energizing the coil 7, the magnetic substance 8 is magnetized, the strong magnetic field is generated in the vicinity of the magnetic substance 8, and the particles 3 inside the dispersion medium 4 whose viscosity is lowered are moved to the surface side of the medium F by the generated magnetic field, whereby image information is printed.  Thus, a printing erasing head has structure that the medium F is heated and the particles 3, are attracted by one head.

SOLUTION: In case of converting the oxygen concentration to be measured by a λ sensor 145 to an air-fuel ratio, correction is performed while considering influence of the increase of moisture in the air. As a first measure, a quantity QL for characterizing a mass of fresh air is corrected while considering a moisture rate and the mass of the fresh air is corrected so that the only effective dry component of the mass of the fresh air takes a part of the signal QLIK. As a second measure, a target value QLS for the mass of the fresh air is corrected in dependence on the moisture in the air so as to control or adjust an exhaust gas recirculation unit 160. As a third measure, air-fuel ratio is corrected in dependence on the moisture in the air. With this method, accuracy of the recirculation of the exhaust gas is improved, and generation of the exhaust gas can be lowered.
